HK Government’s IPv6 NTP Server at time.hko.hk

In the past 3 days, I was working with colleagues in the Hong Kong Observatory to find out the problem of their IPv6 NTP system. The system could not accept NTP request while "ntpdate -d -v 2407:8000:8001:80::8" showed that the host was found.

After many hours of testing and troubleshooting, we were sure that there was a bug in the firmware of the new atomic clock system which affected v6 network connectivity. However, we applied a temporary fix to make things work in a stable manner. The system could be accessed now.

I like to thank colleagues of CUHK, OGCIO and OFTA for helping the end-to-end testing and fault-finding in the past 3 days.

Now that the system is normal, I can do "ntpdate -6 time.hko.hk" to conduct time sync over v6 network.

About Me

This planet is sick. Just look at the place I am living. The global warning effect has turned Hong Kong into a place with no winter. I like winter more than any other seasons. There is a big price to pay if we continue to ignore our global environment. Please, for the sake of your next generation, consume less paper, less fuel and do not use excessive plastic bags.
A simple life is definitely better than a luxurious life.
